> Key: HBASE-7323
> URL: https://issues.apache.org/jira/browse/HBASE-7323
> Project: HBase
> Issue Type: Sub-task
> Components: Compaction, Performance, regionserver, Scanners
> Affects Versions: 0.96.0

> SeekerState is the staging site for a Cell while it is being assembled by the
> BufferedEncodedSeeker. When the parent StoreFileScanner calls
> getCurrentCell() it's guaranteed that the Cell is fully assembled, and we can
> directly return the SeekerState as a Cell rather than copying it into a
> KeyValue. A benchmark at the StoreFileScanner level show ~50% faster
> cells/sec than when copying to KeyValues (ignoring garbage collection).
